Answer

Explanation:

Step1: Determine barium's oxidation state

Barium (Ba) is in Group 2 of the periodic - table, so it has an oxidation state of +2.

Step2: Analyze the formula requirements

In the formula BaX₂, the overall charge of the compound must be zero. Since Ba has a +2 charge, the total negative charge from 2X must be -2. So, the oxidation state of X must be -1.

Step3: Identify elements with - 1 oxidation state

Elements in Group 17 (halogens) have an oxidation state of -1 in ionic compounds. Chlorine (Cl), iodine (I), and fluorine (F) are halogens.

Answer:

B. Chlorine, iodine, and fluorine
